9 clrbuf \- erase the contents of a buffer

18 \fBvoid\fR \fBclrbuf\fR(\fBstruct buf *\fR\fIbp\fR);
24 Architecture independent level 1 (DDI/DKI).
32 Pointer to the \fBbuf\fR(9S) structure.
38 The \fBclrbuf()\fR function zeros a buffer and sets the \fBb_resid\fR member of
39 the \fBbuf\fR(9S) structure to \fB0\fR. Zeros are placed in the buffer starting
40 at \fIbp\fR\fB\(->b_un.b_addr\fR for a length of \fIbp\fR\fB\(->b_bcount\fR
41 bytes. \fBb_un.b_addr\fR and \fBb_bcount\fR are members of the \fBbuf\fR(9S)
46 The \fBclrbuf()\fR function can be called from user, interrupt, or kernel
51 \fBgetrbuf\fR(9F), \fBbuf\fR(9S)
